The Lightweight Access Point 1242/1131 is a two-radio Wi-Fi
infrastructure device for selected indoor deployments. It is a Lightweight
Access Point Protocol (LWAPP)-based product. It provides a 2.4 GHz radio and a
5.8 GHz radio compatible with 802.11b/g and 802.11a. One radio can be used for
local (client) access for the access point (AP) and the second radio can be
configured for wireless backhaul. LAP1242/LAP1131 supports P2P, P2MP, and mesh
type of architectures.
Make sure to read through the guide before attempting any of the
This document describes the deployment of Enterprise Wireless Mesh for
indoor mesh. This document will enable wireless end-users to understand the
fundamentals of Indoor Mesh, where to configure indoor mesh, and how to
configure indoor mesh. Indoor mesh is a subset of Cisco Enterprise Wireless
Mesh deployed using wireless controllers and lightweight APs.
Indoor mesh is a subset of the Enterprise mesh architecture deployed on
Unified Wireless architecture. Indoor mesh is in demand today. With indoor
mesh, one of the radios (typically 802.11b/g) and/or the wired Ethernet link is
used to connect to clients, while the second radio (typically 802.11a) is used
to backhaul client traffic. The backhaul may be a single hop or over multiple
hops. Indoor mesh brings these values to you:
Not having to run Ethernet wiring to each AP.
Ethernet switch port is not required for each AP.
Network connectivity where wires cannot provide
Flexibility in deployment – not restricted to 100m from an Ethernet
Easy to deploy an ad-hoc wireless
Big-box retailers are very attracted to indoor mesh because of the
costs savings on wiring as well as for the reasons previously mentioned.
Inventory specialists use it n performing inventory counts for
retailers, manufacturing plants, and other companies. They want to quickly
deploy a temporary Wi-Fi network at a customer site to enable real-time
connectivity for their handheld devices. Educational Seminars, conferences,
manufacturing, and hospitality are some of the places where indoor mesh
architecture is needed.
When you finish reading this guide, you will understand where to use
and how to configure indoor mesh. You will also understand that indoor mesh in
NEMA enclosures is NOT a replacement for outdoor mesh. Further, you will also
understand the superiority of indoor mesh over link role flexibility (single
hop mesh) used by autonomous APs.
You have knowledge of Cisco Unified Wireless Network, architecture, and
products. You have knowledge of Cisco Outdoor Mesh products and some of the
terminology used for mesh networking.

The Cisco Indoor Mesh Network Access Point is a two-radio Wi-Fi
infrastructure device for selected indoor deployments. It is a Lightweight
Access Point Protocol (LWAPP)-based product. It provides a 2.4 GHz radio and a
5.8 GHz radio compatible with 802.11b/g, 802.11a standards. One radio
(802.11b/g) can be used for local (client) access for the AP and the second
radio (802.11a) can be configured for wireless backhaul. It provides an indoor
mesh architecture, where different nodes (radios) talk to each other via
backhaul and also provide local client access. This AP can also be used for
point-to-point and point-to-multipoint bridging architectures. The Wireless

Indoor Mesh Software
Indoor Mesh Software is a special release as it concentrates on the
indoor APs, especially indoor mesh. In this release, we have both the Indoor
APs working in Local mode and also in bridge mode. Some of the features that
are available in 220.127.116.11 release are not implemented in this release.
Improvements have been made to the command line interface (CLI), graphical user
interface (GUI – web browser) and on the state machine itself. The objective
for these improvements is to gain valuable information from your perspective
regarding this new product and its functional viability.
Indoor mesh specific enhancements:
Indoor Environment – Indoor mesh is implemented
using LAP1242s and LAP1131. These are implemented in indoor environments where
Ethernet cable is not available. The implementation is easy and faster to
provide a wireless coverage to remote areas within the building (for example,
Retail Distribution centers, Education for Seminars/conferences, Manufacturing,
Bridge Group Name (BGN) Enhancements – In order to
allow a network administrator to organize a network of Indoor Mesh APs into
user specified sectors, Cisco provides a mechanism called Bridge Group Name, or
BGN. The BGN, really the sector name, causes an AP to connect to other APs with
the same BGN. In the event an AP finds no suitable sector matching its BGN, the
AP operates in default mode, and chooses the best parent that responds to the
default BGN. This feature has already received a lot of appreciation from the
field as it fights against the stranded AP conditions (if someone has
mis-configured the BGN). In the 18.104.22.168 software release, the APs, when using
the default BGN, does not operate as an indoor mesh node and does not have any
client access. It is in maintenance mode to access via the controller, and if
the administrator does not fix the BGN, the AP will reboot after 30
Security Enhancements - Security on indoor mesh code
is by default configured for EAP (Extensible Authentication Protocol). This is
defined in RFC3748. Although the EAP protocol is not limited to wireless LANs
and can be used for wired LAN authentication, it is most often used in wireless
LANs. When EAP is invoked by an 802.1X enabled NAS (Network Access Server)
device such as an 802.11 a/b/g Wireless Access Point, modern EAP methods can
provide a secure authentication mechanism and negotiate a secure PMK (Pair-wise
Master Key) between the client and NAS. The PMK can then be used for the
wireless encryption session which uses TKIP or CCMP (based on AES)
Prior to the 22.214.171.124 software release, outdoor mesh APs used
PMK/BMK to join the controller. This was a three-cycle process. Now the cycles
are reduced for a faster convergence.
The overall goal of indoor mesh security is to provide:
Zero touch configuration for provisioning
Privacy and authentication for data frames.
Mutual authentication between the network and the
Ability to use standard EAP methods for authentication of indoor
mesh AP nodes.
Decoupling LWAPP and indoor mesh
The discovery, routing, and syncing mechanisms are enhanced from the
current architecture to accommodate the required elements to support the new
Indoor mesh APs discover other mesh APs by scanning and listening for
gratuitous neighbor updates from other mesh APs. Any RAP or indoor MAPs
connected to the network advertises core security parameters in their NEIGH_UPD
frames (much like 802.11 beacon frames).
Once this phase is over, a logical link between an indoor mesh AP and
root AP is established.
Indoor Mesh Alarms have been added.
Indoor Mesh Reports can be generated showing the hop count, worst

Note: MAC filtering is enabled by default.
In a text file, record the MAC addresses of all the indoor mesh AP
radios you deploy in your network. The MAC address can be found on the back of
the APs. This helps you for future testing, as most of the CLI commands require
the APs MAC address or names be entered with the command. You can also change
the name of the APs to something more easily remembered, such as, “building

There are two primary radio roles possible with this solution:
Root Access Point (RAP) - The radio with which you want to connect to
the Controller (via switch) will take the role of a RAP. The RAPs have a wired,
LWAPP-enabled connection to the Controller. A RAP is a parent node to any
bridging or indoor mesh network. A controller can have one or more RAP, each
one parenting the same or different wireless networks. There can be more than
one RAP for the same indoor mesh network for redundancy.
Indoor Mesh Access Point (MAP) - The radio which has no wired
connection to the Controller takes the role of a indoor mesh AP. This AP was
formerly called Pole top AP. MAPs have a wireless connection (through the
backhaul interface) to perhaps other MAPs and finally to a RAP and thus to the
controller. MAPs may also have a wired Ethernet connection to a LAN and serve
as a bridge endpoint for that LAN (using a P2P or P2MP connection). This can
occur simultaneously, if configured properly as an Ethernet Bridge. MAPs
service clients on the band not used for the Backhaul Interface.
The default mode for an AP is MAP.
Note: The radio roles can be set via GUI or CLI. The APs will reboot after
the role change.
Note: You can use the Controller CLI to pre-configure the radio roles on an
AP provided the AP is physically connected to the switch or you can see the AP
on the switch as a RAP or a MAP.
Bridge Group Names (BGN) controls the association of the APs. BGNs can
logically group the radios to avoid two networks on the same channel from
communicating with each other. This setting is also useful if you have more
than one RAP in your network in the same sector (area). The BGN is a string of
ten characters maximum.
A factory-set bridge group name is assigned at the manufacturing stage
(NULL VALUE). It is not visible to you. As a result, even without a defined
BGN, the radios can still join the network. If you have two RAPs in your
network in the same sector (for more capacity), it is recommended that you
configure the two RAPs with the same BGN, but on different channels.
Note: Bridge Group Name can be set from the Controller CLI and GUI.
After configuring the BGN, the AP will reset.
Note: The BGN should be configured very carefully on a live network. You
should always start from the farthest node (last node) and move towards the
RAP. The reason is that if you start configuring the BGN somewhere in the
middle of the multihop, then the nodes beyond this point will be dropped as
these nodes will have a different BGN (old BGN).
You can verify the BGN by issuing this CLI command:
(Cisco Controller) > show ap config general <apname>
Also, you can configure or verify the BGN using the Controller

If you are collocating RAPs, we recommend you use alternate adjacent
channels on each RAP. This will reduce co-channel interference.
In an indoor mesh network we must verify the Parent-Child relationship
between the nodes. Hop is a wireless link between the two
radios. The Parent-Child relationship changes as you travel through the
network. It depends upon where you are in the indoor mesh network.
The radio closer to the controller in a wireless connection (hop) is a
Parent of the radio on the other side of the hop. In a
multiple hop system there is a tree-type structure where the node connected to
the Controller is a RAP (Parent). The immediate node on the
other side of the first hop is a Child, and subsequent nodes
in the second hop onwards are the Neighbors for that

login failure for three consecutive times.

It is possible that an AP is wrongly provisioned with a
“bridgegroupname” for which it was not intended. Depending on the network
design, this AP may or may not be able to reach out and find its correct
sector/tree. If it cannot reach a compatible sector, it may become
In order to recover such a stranded AP, the concept of
‘default’ bridgegroupname was introduced with the 3.2.xx.x code. The
basic idea is that an AP that is unable to connect to any other AP with its
configured bridgegroupname, attempts to connect with “default” (the word) as
bridgegroupname. All nodes running 3.2.xx.x and later software accept other
nodes with this bridgegroupname.
This feature can also help in adding a new node or a wrong configured
node to a running network.
If you have a running network, take a preconfigured AP with a different
BGN and make it join the network. You will see this AP in the controller using
“default” BGN after you add its MAC address in the
The AP using the default BGN can act as a normal Indoor Mesh AP

WCS will generate these alarms and events related to the indoor mesh
network based on the traps from the Controller:
Click Mesh Links. It will show all the alarms related
to indoor mesh links.
These Alarms apply to indoor mesh links:
Poor link SNR - This alarm is generated if link SNR falls below 12db.
The user cannot change this threshold. If poor SNR is detected on the backhaul
link for child/parent, the trap will be generated. The trap will contain SNR
value and the MAC addresses. Alarm Severity is Major. SNR (signal-to-noise)
ratio is important because high signal strength is not enough to ensure good
receiver performance. The incoming signal must be stronger than any noise or
interference that is present. For example, it is possible to have high signal
strength and still have poor wireless performance if there is strong
interference or a high noise level.
Parent changed - This alarm is generated when the child moved to
another parent. When the parent is lost, the child will join with another
parent, and the child will send a trap containing both old parent and new
parent’s MAC addresses to WCS. Alarm Severity: Informational.
Child moved - This alarm is generated when WCS gets a Child lost
trap. When the parent AP detected its loss of a child and not able to
communicate with that child, it will send a Child lost trap to WCS. The trap
will contain the child MAC address. Alarm Severity:
MAP parent changed frequently - This alarm is generated if Indoor
Mesh AP changes its parent frequently. When MAP parent-change-counter exceeds
the threshold within a given duration, it will send a trap to WCS. The trap
will contain the number of times of MAP changes and the duration of the time.
For example, if there are 5 changes within 2 minutes, then the trap will be
sent. Alarm Severity: Informational.
Child Excluded Parent - This alarm is generated when a child
blacklisted a parent. A child can blacklist a parent when the child failed to
authenticate at the Controller after a fixed number of attempts. The child
remembers the blacklisted parent and when the child joins the network, it will
send the trap which contains the Blacklisted Parent MAC address and the
duration of the blacklist period.
Alarms other than indoor mesh links:
Console Port Access - The console port provides the ability for the
customer to change the user name and password to recover the stranded outdoor
AP. However, to prevent any authorized user access to the AP, WCS needs to send
an alarm when someone tries to log in. This alarm is required to provide
protection as the AP is physically vulnerable while located outdoors. This
alarm will be generated if the user has successfully logged in to the AP
console port, or if he has failed three consecutive times.
MAC Authorization Failure - This alarm is generated when AP tries to
join the Indoor Mesh but fails to authenticate because it is not in the MAC
filter list. WCS will receive a trap from the Controller. The trap will contain
the MAC address of the AP which failed

Mesh Node Hops
Packets error Stats
Worst Node Hop
Indoor Mesh AP typically has more than one neighbor. In the case that
an indoor mesh AP looses its parent link, the AP should be able to find the
alternate parent. In some case, if there are no neighbors shown, then the AP
will not be able to go to any other parents if it looses its parents. It is
critical for the user to know which APs do not have alternate parents. This
report lists out all the APs which do not have any other neighbors other than
the current parent.
This report shows the number of hops away from the Root AP (RAP). You
can create the report based on these criteria:
AP By Controller
AP By Floor
The packet errors can be caused by interference and packet drops. The
packet error rate calculation is based on packets sent and packets successfully
sent. The packet error rate is measured on the backhaul link and is collected
for both neighbors and the parent. The AP periodically sends packet info to the
Controller. As soon as the parent changes, the AP sends out the collected
packet error info to the Controller. WCS polls packet error information from
the Controller every 10 minutes by default and stores it in the database for up
to 7 days. In WCS, the packet error rate is shown as a graph. The packet error
graph is based on the historical data stored in database.
This report shows the counter values of neighbor total transmit packets
and Neighbor Total packets successfully transmitted. You can create the report
based on certain criteria.
Noise problems might occur at different times and noise might increase
at different rates or last for different lengths of time. The next figure
provides the ability to create report for both Radio a and b/g as well as
selective interfaces. The report lists the 10 worst SNR links by default. You
can choose from 5 to 50 worst links. The report can be generated for the last 1
hour, last 6 hours, last day, last 2 days, and up to 7 days. The data is polled
every 10 minutes by default. The data is kept in database for maximum seven
days. The neighbor Type selection criteria can be All Neighbors,
This report lists the10 worst hops APs by default. If the APs are too
many hops away, the links could be very weak. The user can isolate the APs
which have many hops away from Root AP and take appropriate action. You can
